THREHADIING DEVICE FOR SHUTTLES.

942,263. spemcaaon of To all whom it may concern:

r.Be it known that I, JAMEs JORDAN, of the city of Montreal, ProvinceofQuebec, Canada, have invented certain new and use` V:ful Improvements inThreading Devices for construction of parts herein described vandclaimed and illustrated in the accompanying drawings in which similarreference characters indicate the same parts and wherein- Figure 1 is aplan view of the top of the threader end of a shuttle provided with myinvention; Fig. 2 is a side elevation thereof;

Figs. 3 and 4 are detail side elevations of the thimble of my imroven-device, the respective views being ta en at right angles to eachother; Fig. 5 is a transverse vertical sectional view taken on line A,A, Figs. 1, 2, and. 6; Fig. 6 is a vertical axial sectional view takenwith the shuttle reversed, the point being shown in elevation; Fig. 7 isa planview of -the thimble; Fig. 8 is a transverse vertical sectionalview taken on lines B, B, Figs. 1, 2 and 6. Fig. 9 is a vertical axialsectional view of the opposite end of the shuttle; Fig. 10 is a planview of Ithecomplete shuttle; and Fig. 11 is `a plan view, of theunderside of the threader end. t

The shuttle is of the well known form at present in use and has as usualthe well b for the cop c, and axial 'and transverse threading eyes e and0l respectively.

The invention resides in the means for threading the shuttle eyes andthe means for securing in place the spindle for carrying the cop:

improved threading device comprises a thimble embedded in oneend of theshuttle, and a particular formation of such end to present parts adaptedto eoaetwi h por-L tions of the thimble to guide the thread into theeyes of the shuttle and prevent acci-i dental unthreading; while my imroved spindle-joint comprises a member \or1ned integrally therewith andadapted to be held in position entirely by the usual removable sprlng.

More` specifically speaking the thimblel (indicated at l0) is ofcylindrical form and has a pair of eyes f andg from .which verticalslots la. and z' extend tangentially to the Letters Patent. PatentedDeo. '7, '1909.

top end of the thimble, such slots extending from the sides adjacent toeach other of the eyes, the rear and underside of the'portion lo havinga notch n, and the underside of the portionl a notch o. Another featureof this thimble is that it is screw threaded and has smooth portions pand g leading to the eyes.

The shuttleis formed, with a tapped boring slightly greater in depththan the thimble is 1n axial length, and adapted to have the latterscrewed thereinto, and receive a closing plug r; and the eyes of thisthimble and e of the shuttle when such thimble is screwed into place.

The sides 40 of the end of the cop-well adjacent to my improvedthreading device converge and terminate o1' merge in a trans-V verseportion in which the eye e is formed. A slot is cut in the head oftheshuttle and extends from the eye e to the eye d. This slot commences inthe cop-well intersecting one of the converged sides 40, and it extendsfirst parallel to the axis of the shuttle as at 2O then diagonally as at20a, and finally curves around the shoulder ofthe shuttle head as at 20band joins the forward end of a second. slot 22 cut horizontally (Figs.2, 5, 6,' and' 8) land extended inwardly until it meets the slot20,201,201, while the portions 2Oa and 20? of the latter slot are cutdiagonallyl downward and away from the side of the shuttle having theslot 22 therein, in order to present an' .eifective obstruction'21 tothe displacement of the thread from the 'slot h. The two slots 20, 20L1and 2()b and 22 form a deep gill 24 the point and sides whereof arerounded to prevent its tripping upon the threads or parts of the loom itcrosses during action.

v'.llhe preferred specic embodiment of the spindle-joint feature of myinvention conbutt of the spindle and presenting a hook 31 with its endturned outward as at 32 to engage beneath a. shoulder, `and a shoulder34 adapted to have the usual spring 35 bear thereon, while theundersideof such head is flat to rest upon a part 36 formed within the shuttlevbody which is recessed asv at 37 to allow the end 32 of the hookfreedom to swing when the spindle is turned to its dotted position (Fig.9) for the purpo'se o f changing the cop. A. pin 38 is mountedpermanently in the shuttle andl is ada ted to have the head 30 hooked.therebver efore'tho spring are so located as to coincide with the eyes0lA sist-'s of a head 30 formed integrally with the is put in lace, andthe space between such pin and. t e shoulder 33 is made just suficientto allow the said end of the hook to be introducedinto position. Thisjoint enables the spindle to be removed at will without the necessity ofdisplacing the pin 38 and by simply'loosening the spring 35 and swingingit to one side. The pin is preferably made of wood and soaked in oil.

In threading a shuttle provided with my invention the thread is takenfrom the cop.

and drawn downwardly over the gill-side of the point, it being thuscaused to run down one of the converging sides 40, enter the mouth ofthe slot 20 and then fall behind the ill and rest momentarily upon theinner end of the thimble. It is then drawn horizontally toward theopposite end of the slot and by this across lsuch inner end. of thethimble and down the inclined portions c and Z thereof to the abutment mwhich deeets it into the eyes f and g, thus completing the threadingaction.

The portion 210 of the slot 22 beyond .the eye al accommodates 'as theshuttle travels in the cated in Fig. 2. t

My improved arrangement of the shoulder 34, which causes the spring toexert pressure tending to pressthe spindle down, enables such spring toyieldingly retain the extending the thread direction indi- 'spindle inits position in the cop well and 1n its position` ready to change thecop, in which two positions of the spindle the spring bears lightly onthe top and inclined forward face of such shoulder, respectively. Thusthe spring is in Jfull tension only while the spindle is actually beingchanged from one position to the other.

What I claim is as follows:
